This video will show how to make a vacuum pump, a device that can be used to suck the air out of sealed environments.
A clear vacuum chamber such as the one seen in the video can be obtained by purchasing a bell jar and vacuum plate, easily available online. I highly advise that only vessels made for handling vacuum pressure such as bell jars be used with this or any vacuum pump. If a vessel were to fail while under vacuum the implosion can be powerful enough to cause injury.
